They arrived in Lausanne with swagger, but looked far from a title contender after only narrowly scraping past Dusseldorf LFDY (GER) before losing to hosts Lausanne (SUI) on Day One.
But Antwerp weren't worried and peaked when it mattered most during the knockout stages, where Jonas Foerts announced himself on the big stage with 11 points and the Maurice Lacroix Buzzer Beater to down Liman Huishan NE in an epic quarter-final.
Red-hot Miami (USA), fresh from ending Ub Huishan NE's amazing winning run, were next but Antwerp shut down superstar Jimmer Fredette to record the dub then silenced the home fans to exact revenge over Lausanne (SUI) in a tense final.
The 26-year-old Foert has provided a spark in his return to Antwerp this season and deservedly walked off with the MVP after a lights out display where he top-scored with 43 points and finished No.1 in player value (46.1).
Perhaps the happiest dude was Dennis Donkor, the team's heart and soul, who has put everything on the line this season and was understandably jumping for joy when Antwerp's second ever Masters title was secured.
If anyone was going to take down unstoppable Ub - winners of 6 of 6 Masters this season - it was probably going to be 'Jimmer Mania'.
Ub's historic run - where they won 31 of 32 World Tour games - finally ended in the quarter-finals when former NBA player Jimmer Fredette caught fire to sink 6 two-pieces on his way to a ridiculous 13 points.
It was sweet revenge for Fredette, who had the heartbreak of narrowly missing the game-winner against Serbia to win the FIBA 3x3 World Cup 2023.
It seemed like Miami were well on their way to a first title before being shut down by Antwerp in the semis.
The much-hyped Miami have played in six events - including two Masters - but still are yet to taste the ultimate success.
But after at least proving Ub are beatable, Miami are inching closer to the title the American newcomers so desperately crave.
